FELLY FOR WIEEELS WITH PNEUIVIATIC TIRES.v

Specification of Letters Patent.

l vpatented June 22, '1909.

Application filed November 9, 1906. Serial No. 342,609.

To all whom it may concern:

Be it known that I, TnEoDoR BRUCKNER, subject of the Emperor bfAustria-Hungary, residing at Vienna, Austria-Hungary, have inventedcertain new and useful Improvements in Fellies for Wheels with PneumaticTires, of which the following is a specification. A

This invention relates to a rim for Wheels with pneumatic tires, inparticular for autoF mobile wheels in which the pneumatic tire is fittedupon a wheelrirn that is adapted to be slid together with the air valveand the screws for fastening the neumatic tire, laterally upon the fellyan is held rigidly fast between two annular flanges; of these flangesthe interior flange forms one piece with the A felly whereas theexterior flange constitutes a flanged ring that can be nected with theAfelly. i

The invention has for its purpose the strengthening of the felly atthose places in which radial slits must be provided for the reception ofthe screws for attaching the pneu-.

detachably con- I matic tire and of the air valve in order to enn ablethe easy and unobstructed application and removal of the Wheel rim.

According to the present invention and in contradistinction to the knownarrangements the parts above referred to thatare weakened by the slitsare strengthened by means of angie-iron pieces the outer extremities ofwhich are bent around and down upon the felly while their interiorextremities overlap eachl other. The angle irons -are fitted on thefelly while they are in a heated condition and form a protecting ironcovering inseparably connected with the felly. The interior angle ironforms partof the interior annular iiange Whereas the outer angle ironconstitutes part of the supporting bearing for the removable flangedring whereby the wheel rim that carries the pneumatic tire is securelyand rigidly maintained in position between the two annular flanges. Y jl The' accompanying drawings represent a wheel-according to the presentinvention.

vFigure l shows the wheel in lateral elevation and partly in section andFigs. 2 and 3 represent respectively sectional views on the lines E-Fand G-H of 1.

The pneumatic tire a is fitted upon the iron wheel rim bthat can be slidThe latter is provided on its interior side adjacent to the carriagewith a projecting an- /my hand in presence of onto the felly e.`

nular flange forming'an inseparable part with the felly whereas-on theexterior side it 1s provided with radial slits g serving for thereception of the air valve c and of the screws d intended for securingthe pneumatlc t1re 3 in this manner the wheel rim can slid onto thefelly e. For securingthe wheel rim u on the felly and for preventing aturning ol the former, it is provided Wlth ribs h engaging correspondingrooves. of an 1r on ring fastened tothe elly. The Wheel r1m is heldrigidly in osition by means of an exterior annular ange lc removablyconnected with the felly e by vthreaded bolts l. Those parts of thefelly e which are weakened bythe said slits g are strengthened by meansof angle irons n, o, the exterior ends of which are bent 'around-anddown onto the felly whereas their 'nterior ends form a slant'- ing jointat the in erior surface of the felly .and consequently these ends overlaeach other. At this joint as Well as on tle'side surfaces the angleirons are fastened to the felly by screws p. The interior an le iron nconstitutes part of the interior annu ar flange f whereas the exteriorangle iron io formsA part of the supporting bearing for the annular flane 7c.

T e an le irons are slotted or contain openings to a ow the valve-steinand security bolts d to be passed into the slots in the felly.

Claim.`

In a vehicle wheel thel combination with 6i be easily to be slidthereon, av neumatic tire mounted on said wheel-rim, t e` saidfelly'having slits therein for the reception ofscrews .and the air valveof the neumatic tire, angleirons secured to the wheehrim for reinforcingthe same, the said an le irons'having theirjouter ends' bent aroun anddown ontothe, felly and their beveled inner ends overlapping .eachother, forming aslanting joint, a-removable annular flange for holdingthe wheel-rim in position on the said felly and means for securing thesaid annular flange to the said felly.V

In testimony whereof I have hereunto set two subscribing wit- IIGSSES.
